Choosing the Right Carriage Bolt: Plain vs. Zinc Plated?

Our A307 carriage bolts are available in various platings, including plain and zinc, to suit a wide range of project specifications.

• Plain Finish: These low-cost fasteners have a natural finish, exposing the carbon steel composition. They're ideal for indoor applications or low-moisture environments where corrosion resistance isn't a primary concern.
• Zinc-Plated: Zinc and zinc-yellow platings serve as a protective coat over the steel fastener. These finishes make the carriage bolts suitable for outdoor use and can provide enhanced durability in high-moisture environments.

Let the team at Fasteners Etc., Inc. help determine which finish is best for your unique application. We can also assist with a custom inventory management program through our business solutions for all your fasteners needs.
